Transponders are mandatory for 2010 During the meeting on Tuesday January 13th 2009, the Members and Board Members who attended voted to mandate the use of transponders for the 2010 year to score our race events. All Bay OTHG members will need to purchase their personnel transponder from the club for $215.00 (while supplies last), or $252.00. Keep in mind this is the same unit that both AMP and EstreetMX use and are compatible with there systems.  We will have a limited supply for rent at each local event but strongly encourage each member to purchase his or her own personal unit.  This unit will be associated with you in the software and will expedite registration and recognize your unit every time you cross the scoring loop. Scoring loops will be installed at every track we race. The daily rental fee has not been determined as of yet. Here is a link to the site for the system we have chosen: http://www.amb-it.com/motocross-c-7.html The units are warranted for three years and are rechargeable.  Life span is expected to be well in excess of 5 years.  The units attach to your left fork using the included clip. Each member will be required to have a unit on their bike at our events, fully charged.  Members racing there Eval race are not to use a transponder. Only classified OTHG Members need to use the transponder. Our support classes do not require a transponder. If you have any questions, please contact a Board Member.
